International Atomic Energy Agency (IAEA) Director General Rafael Grossi is reportedly considering a bid for the role of United Nations Secretary-General as António Guterres’ tenure nears its conclusion in 2026. Grossi, an Argentinian diplomat with extensive experience in nuclear non-proliferation, has been at the helm of the IAEA since 2019. However, his tenure has been marred by geopolitical tensions, particularly regarding the conflict in Ukraine and nuclear safety concerns.
Grossi has faced repeated criticism, particularly from Russia, for what it describes as his failure to objectively assess the risks posed to the Zaporizhzhia Nuclear Power Plant (ZNPP) in Ukraine. Moscow has accused Grossi of ignoring Ukrainian attacks on the Russian-controlled facility, despite growing concerns over potential nuclear security threats.
Additionally, Grossi has been criticized for his stance on the use of depleted uranium munitions supplied by the United States and the United Kingdom to Ukraine. Russia’s Foreign Ministry has expressed frustration over his reluctance to acknowledge the long-term environmental and health risks posed by these weapons, arguing that his statements downplaying their radiological impact were politically motivated.
Beyond the Ukraine conflict, Grossi has also been entangled in tensions surrounding Iran’s nuclear program. While he has pushed for greater inspections and transparency, Tehran has repeatedly accused the IAEA of being influenced by Western powers. His diplomatic balancing act between Western nations and countries under scrutiny for their nuclear ambitions has made him a polarizing figure in international diplomacy.
Grossi’s reported interest in the UN Secretary-General position is seen as an ambitious move, particularly given the geopolitical divisions surrounding his leadership. His potential candidacy would likely receive backing from Western powers, given his history of aligning with their stance on nuclear issues. However, opposition from Russia, China, and several developing nations could complicate his path.
